Ragdoll Collider problem

I have a character that is a Rigid Body, Box Collider, with the standard ragdoll from the Unity Library. I Turn the Rigid Body, Box Collider for the character on, and turn the limbs RigidBody off, Then use Animations for the character. When the character dies, I turn the box collider and rigid body for the character off and turn the rigid bodies for the limbs on....
